The disk.ephemeral.size meter publishes the size of an instance's ephemeral disk (in GB). The disk.root.size meter publishes the size of an instance's root volume (also in GB). Both of these meters are currently available via notifications only. This information is also available in the instance's local VM metadata, so add new pollsters to publish them. This allows for publishing the these two meters with measures at regular intervals if required, rather than relying solely on Nova to send notifications correctly. If a given instance does not change very often, the compute.instance.exists notification would only publish values to these metrics just once per hour, which might not always be sufficient to reliably supply them. These pollsters can be disabled if required by adding "!disk.ephemeral.size" and "!disk.root.size" to the applicable catch-all source in polling.yaml.
